I'm using TestLink v1.9.13 and being in .NET world, I'm making use of "Testlink API V 1.3 binaries" to communicate with TestLink. So far, I'm able to upload and download my automated test cases and their attachments too from the file-system into the TestLink. Also, we have few attachments which need to be uploaded onto the TestSuite which we've been able to achieve it using the 'UploadTestSuiteAttachment' method.

However, there doesn't seem to be a method available to download the TestSuite attachments. Are there any other binaries which need to be consumed? Can someone guide me to derive to a solution?
